LiveData for Cristal

Some updates:

I’ve chosen to keep the edit button visible to make the feature discoverable.

The column header is a bit more complicated, as we need to reserve space for the filters. If we don’t, the column will change height to accommodate the filters on hover. The menu icon, however, can be shown only on hover without any issues.

I’ve changed the icon to the horizontal variation to try reduce the ambiguity with drag-and-drop.

Here’s a slight change in the background color for selected lines.
